Adjust the Pointer Speed slider until the pointer motion
is comfortable for you. You will see one slider per each pointing device,
such as mouse or touchpad.

You can set different pointer speed for each type of device. For example,
you can have one scroll speed for a laptop touchpad and another for a mouse.
Sometimes the most comfortable settings for one type of device are not the
best for another.

The Touchpad section only appears if your system has a
touchpad, while the Mouse section is only visible when a mouse
is plugged in.
